According to our database, Peter CHRISTENSEN, husband of Elsie Catherine MORTENSEN (1815-1854), died in Omaha, Douglas Co., NE. Find A Grave shows he is buried in Mount Hope Cemetery. However, I do not believe this is the correct Peter.
If you read Peter’s biography, written by his granddaughter, Anna (Ellis) LARSEN, he went on to help settle Ephraim, Sanpete Co., in the UT Territory where he married for a second time in 1856.
Unless anyone can provide more substantial documentation to support otherwise, I have corrected Peter and his wife, Anna’s records to be more in line with her biography.
